Even before he is born, your baby's senses are helping him to learn about the world. And he's learning about you too. What he hears, tastes and smells during your pregnancy can help him to recognise you from the moment you first meet.

It all begins very early on. At nine weeks, and still only the size of a grape, your baby's sensory organs such as his nose, eyes and ears are already developing.

By ten weeks his taste buds are forming. As he grows, he'll begin to taste the foods you eat through the amniotic fluid that surrounds him. Eating healthy foods while you're pregnant can help him have a taste for them later on.

It's thought that amniotic fluid plays an important role in bonding too. It has a unique smell that will be similar to your breast milk. It's a familiar smell to your baby, and one he will respond to after he's born.

Although your baby's eyes are developing, he won't see very well as a newborn. It will take him a few weeks to remember what you look like. But he already knows the sound of your voice. He'll recognise your partner's voice, and siblings too if he has them. From about halfway through your pregnancy he can hear you talking and listen to the reassuring beat of your heart. Those familiar sounds will help him to form an attachment to you as you hold him and talk to him in the hours and days after you have given birth.
